Friday the 13th. Just the mention of it can send a shiver down some spines, while others simply roll their eyes and go about their day. But for millions of Americans and countless people around the globe, this date is more than just a square on the calendar—it’s a potent symbol of bad luck, superstition, and, for some, a little bit of fun. With 2026 bringing not just one, but three Friday the 13ths—in February, March, and November—the old superstition is getting more attention than ever.
Where does this uneasy feeling about Friday the 13th come from? According to History.com, the roots are tangled deep in Western folklore and religious tradition. The number 13 has long been considered irregular or even disruptive. Why? Well, 12 is seen as a number of completeness: 12 months in a year, 12 hours on a clock, 12 apostles, 12 tribes of Israel, and so on. Thirteen, by contrast, feels like an odd man out—one too many, or perhaps one too few.
Fridays themselves haven’t always had the best reputation either. In Christian tradition, Friday is a day tinged with sorrow and loss, most notably because it’s believed Jesus was crucified on a Friday. This association, as USA TODAY points out, gave the day a somber undertone long before it ever got paired with the number 13.
The two superstitions—about Fridays and about the number 13—came together over time to form the notorious reputation of Friday the 13th. One historical event often cited as a turning point is the arrest of the Knights Templar. On Friday, October 13, 1307, King Philip IV of France ordered the arrest of hundreds of members of this powerful Catholic military order. Many were tortured and burned at the stake, including the Grand Master Jacques de Molay, who, according to tradition, cursed his persecutors before his execution. As The Independent recounts, this event, combined with the biblical tales, helped cement the date’s reputation for ill fortune.
But the story doesn’t stop there. Norse mythology also plays a role. Loki, the trickster god and the 13th guest at a fateful dinner in Valhalla, is said to have brought chaos and death. The number 13’s reputation as a harbinger of misfortune only deepened as stories like these spread through Europe and beyond, according to USA TODAY.
Modern times have only amplified the superstition. The term "paraskevidekatriaphobia" describes the specific fear of Friday the 13th, while "triskaidekaphobia" is the fear of the number 13 itself. Folklore historian Donald Dossey estimated that between 17 and 21 million people in the United States alone suffer from triskaidekaphobia. The anxiety can be so severe that some experience panic attacks or refuse to work, travel, or make major decisions on this day, as reported by National Geographic.
And it’s not just individuals who are wary. More than 80 percent of high-rise buildings skip having a 13th floor, and many hospitals, hotels, and airports avoid using the number 13 for rooms or gates. The superstition even affects the economy: Dossey told National Geographic that people often refuse to fly, buy houses, or invest in stocks on Friday the 13th, leading to a noticeable slowdown in economic activity.
Of course, Hollywood has had its say, too. The 1980 slasher film Friday the 13th, featuring the masked killer Jason Voorhees, turned the date into shorthand for suspense and horror, spawning a franchise that has grossed over $380 million worldwide, according to Box Office Mojo. The film series has kept the superstition alive for new generations, making Friday the 13th synonymous with thrills, chills, and a little bit of tongue-in-cheek fun.
Despite all the myths and media hype, is Friday the 13th really more dangerous than any other day? The data says no. Both History.com and USA TODAY report that accident and emergency statistics show no significant uptick on this date. Psychologists explain that the belief in bad luck often becomes a self-fulfilling prophecy: people expect trouble, notice mishaps more keenly, and blame the date for anything that goes wrong.
Superstitions about Friday the 13th aren’t limited to this one day, either. From breaking mirrors (said to bring seven years of bad luck) to walking under ladders, spilling salt, crossing paths with black cats, or even stepping on cracks in the sidewalk, people have developed a whole catalogue of rituals to ward off misfortune. Others, meanwhile, embrace lucky charms—four-leaf clovers, horseshoes, rabbit’s feet—or knock on wood to "seal the deal" and keep bad luck at bay, as outlined by USA TODAY.
Weather, too, gets swept into the superstition. In Michigan, for example, Friday the 13th in February 2026 brought mostly sunny skies and crisp temperatures—conditions that, in folklore, are seen as symbols of good fortune and optimism. Rain might be viewed as a wash of misfortune, while snow could mean a peaceful pause for reflection. According to the National Weather Service, the day’s weather in Michigan was a mix of luck and reflection: sunny in the Upper Peninsula and Detroit, with a hint of caution in the air as winds picked up at night.
Interestingly, not everyone views 13 as unlucky. Some pagans see it as a lucky number, representing the number of full moons in certain years. For others, Friday the 13th is just another day—or even a day to celebrate. Celebrities like Mary Kate and Ashley Olsen, Steve Buscemi, Julia Louis-Dreyfus, and Kate Walsh all share a Friday the 13th birthday. And let’s not forget, for some cultures, it’s not Friday the 13th that’s unlucky at all. In Spain and Greece, Tuesday the 13th is the ominous date, while in Italy, it’s Friday the 17th that people avoid.
So, whether you’re carrying a rabbit’s foot, avoiding ladders, or just chuckling at the whole idea, Friday the 13th is a date that continues to fascinate, unsettle, and amuse in equal measure. Its grip on the imagination is as strong as ever, a reminder that sometimes, a little superstition can be a whole lot of fun—or at least a good excuse to take life a bit less seriously, even if just for a day.
